The life expectancy of patients with acute cerebral infarction is related to the severity of the disease, the site of infarction, underlying diseases and complications. Patients with mild hemiplegia generally do not affect their life expectancy, but patients with very severe cerebral infarction or even bedridden patients will have a much shorter life expectancy, which varies from person to person and from disease to disease. Patients with mild acute cerebral infarction can take care of themselves or semi-care for themselves, and their survival is usually not affected by active treatment in the hospital during the acute period, and after discharge, they can insist on exercise, take oral medication on time, and do a good job in secondary prevention of cerebrovascular disease and delaying its redevelopment. However, brainstem infarction, especially medullary infarction involving breathing and heartbeat, can be life-threatening at any time in the acute stage. Patients with severe hemiplegia and long-term bedridden conditions, if improperly cared for and poorly nourished, are prone to complications such as crushing pneumonia, urinary tract infection, arterial and venous thrombosis of the lower extremities, and decubitus ulcers, which, if not corrected and controlled in a timely manner, can seriously threaten the patient’s life and may usually lead to death within months to years. Therefore, patients with acute cerebral infarction must seek timely medical treatment and be actively treated to alleviate or reduce the probability of sequelae and even complications, thereby improving prognosis and prolonging survival.
